Quoted from LTG:
Not a great picture. The red line through the hole shows where a black rubber plug should be.
The blue arrows point to the plate part of the flipper base plate that you can bend back and forth as needed.
This isn't easy. You need to loosen the pawls and get both flippers lined up at rest in the down position besides bending the one plate as needed.
